General Information

NOTE: If the 69609-001 Dual Page/Party

system, the GAI-Tronics Service Department must be contacted to modify the system configuration. If the Dual PPI is being used as a replacement part, proceed as described herein.

Interface (Dual PPI) is being added to an existing installed

Interface PCBA

The 69609-001 Dual PPI is a printed circuit board assembly (PCBA) used to interface Page/Party equipment to the 69254 Series or 69440 Series Master Control Unit (MCU). The Dual PPI PCBA is housed in a 10457 Series Card Rack with the MCU and other associated PCBAs. The Dual PPI will support up to two Page/Party

zones, referred to as “Zone A” and “Zone B.”

Hardware Configuration

Switch and Jumper Settings

Overview

Several switch and jumper settings are required for proper operation of the Dual PPI. The following settings are set during the system commissioning and programming and should not be changed. If replacing an existing Dual PPI for maintenance purposes, be sure to replicate the switch and jumper setting of the card being replaced. Refer to Figure 1 on page 10 for the switch and jumper locations.

Board Address Rotary Switch (SW1) Settings

This switch is used in conjunction with SW4 Position 1 to determine the board addresses used by the

MCU to access the Dual PPI. Since the Dual PPI provides access to two distinct Page/Party

zones, the Dual PPI occupies two separate board addresses – one for Zone A and one for Zone B (assuming that Zone B is enabled). The board addresses for Zone A and Zone B are defined below (expressed as hexadecimal values):

Zone A Board Address

Board Address Example:

2 A 0

/ / /----------Always zero

Equals 2 when SW4 Position 1 is OPEN--------------/ /

Equals 0 when SW4 Position 1 is CLOSED----------/ /

Set by SW1----------------------------------------------------------------/

Zone B Board Address

Board Address Example:

3 A 0

/ / /----------Always zero

Equals 3 when SW4 Position 1 is OPEN--------------/ /

Equals 1 when SW4 Position 1 is CLOSED----------/ /

Set by SW1----------------------------------------------------------------/

Please note that if Zone B is disabled (SW4 Position 2 is CLOSED), then the Dual PPI will only occupy the Zone A board address (the Zone B board address would then be available for use by other cards in the card rack).

Board ID Rotary Switches (SW2 and SW3) Settings

Pub. 42004-729L2A

These switches are used in conjunction with SW4 Positions 4 and 6 to determine the Board ID values for Zone A and Zone B. Since the Dual PPI provides access to two distinct Page/Party

zones, the Dual PPI provides two separate Board ID values – one for Zone A and one for Zone B (assuming that Zone B is enabled). The Board ID values for Zone A and Zone B are defined below (expressed as hexadecimal values):

Zone A Board ID

Board ID Example:

0 1

/ /

Equals 0 when SW4 Position 4 is OPEN--------------/ /

Equals 1 when SW4 Position 4 is CLOSED----------/ /

Set by SW2----------------------------------------------------------------/

Zone B Board ID

Board ID Example:

0 3

/ /

Equals 0 when SW4 Position 6 is OPEN--------------/ /

Equals 1 when SW4 Position 6 is CLOSED----------/ /

Set by SW3----------------------------------------------------------------/

Please note that SW4 Positions 4 and 6 (Extended Board ID A/Extended Board ID B) will only function when SW4 Position 3 (Board Type Select) is in the OPEN position (“Dual PPI” Board Type is selected.) Otherwise, the upper hexadecimal digit of the Board ID values for Zone A and Zone B will be forced to

be “0”. Also, note that each Page/Party

zone associated with a given card rack must be assigned a unique Board ID value to allow it to be clearly identified by the MCU. For sake of simplicity, the Board ID values are typically set to match the zone numbers as defined in the system.

Board Configuration DIP Switch (SW4) Settings

Board Configuration DIP Switch SW4 contains eight positions that control various aspects of board operation in the associated system. The function of each position is detailed below.

Position 1: Board Address Range Select

This switch is used in conjunction with rotary switch SW1 to determine the board addresses used by the MCU to access the Dual PPI. Refer to the “Board Address Rotary Switch (SW1) Settings” section on page 2 for more information.

Position 2: Zone B Disable

This switch may be used to “hide” Zone B from the MCU. This feature may be desirable in cases where only one of the two available zones on the Dual PPI will be utilized by the system. Set the switch according to the following table:

OPEN CLOSED

Zone B is Enabled.

Zone B is Disabled (not visible to the MCU)

Position 3: Board Type Select

This switch determines the Board Type that the Dual PPI will report to the MCU by both Zone A and

Zone B. The Dual PPI has the ability to either report as a Page/Party

Page/Party

OPEN CLOSED

Interface (Dual PPI). Set the switch according to the following table:

“Dual PPI” Board Type is selected.

“PPI” Board Type is selected.

Interface (PPI), or as a Dual

OTE: Upon initial release of the Dual PPI Card, always set switch position 3 to the closed position for

“PPI” board type. The “Dual PPI” board type is reserved for future use pending release of compatible MCU firmware.

Position 4: Extended Board I D A

Interface PCBA Page: 5 of 16

Pub. 42004-729L2A

This switch is used in conjunction with rotary switch SW2 to determine the Board ID value for Zone A. Refer to the “Board ID Rotary Switches (SW2 and SW3) Settings” section on page 3 for more information.

Position 5: FSK Test Mode Enable A

This switch may be used to force activation of the FSK carrier signal at Zone A. A continuous alternating

1-0 data pattern at 2400 bps is produced. This switch must be left in the OPEN position for normal

system operation. The following table defines the operation of this switch:

OPEN

FSK Test Mode for Zone A is Disabled (Must be left in this position for normal operation.)

CLOSED

FSK Test Mode for Zone A is Enabled.

Position 6: Extended Board ID B

This switch is used in conjunction with rotary switch SW3 to determine the Board ID value for Zone B. Refer to the “Board ID Rotary Switches (SW2 and SW3) Settings” section on page 3 for more information.

Position 7: FSK Test Mode Enable B

This switch may be used to force activation of the FSK carrier signal at Zone B. A continuous alternating

1-0 data pattern at 2400 bps is produced. This switch must be left in the OPEN position for normal

system operation. The following table defines the operation of this switch:

OPEN

FSK Test Mode for Zone B is Disabled (Must be left in this position for normal operation.)

CLOSED

FSK Test Mode for Zone B is Enabled.

Position 8: Reserved

This switch is currently unused by the Dual PPI and should be left in the OPEN position.

Page Balance Select (Zone A) Jumper (P6) Settings

This jumper allows the Dual PPI’s internal page balance for Zone A to be disabled in cases where use of a page balance external to the Dual PPI is desired. Note that if an external page balance is used, however, it

must be located in proximity to the card rack. In general, this jumper should be left in the “EN” position

(internal page balance enabled). Set the jumper according to the following table:

EN DIS

Internal Page Balance is Enabled (Should be left in this position for most installations.)

Internal Page Balance is Disabled.

NOTE: If this jumper is set to the “DIS” position, then the Page Balance adjustment for Zone A will have

no effect.

Page Balance Select (Zone B) Jumper (P7) Settings

This jumper allows the Dual PPI’s internal page balance for Zone B to be disabled in cases where use of a page balance external to the Dual PPI is desired. Note that if an external page balance is used, however, it

must be located in proximity to the card rack. In general, this jumper should be left in the “EN” position

(internal page balance enabled). Set the jumper according to the following table:

EN DIS

Internal Page Balance is Enabled (Should be left in this position for most installations.)

Internal Page Balance is Disabled.

NOTE: If this jumper is set to the “DIS” position, then the Page Balance adjustment for Zone B will have

no effect.

Monitor Bus Transmit/Receive (Zone A) Jumper (P8, P9, P12) Settings

These three jumpers may allow Zone A page line audio to drive the monitor bus. Alternatively, these jumpers may allow audio on the monitor bus to drive the Zone A page line. A third option that these jumpers provide is complete isolation between the monitor bus and the Zone A page line. These three options are summarized in the following table:

Option P8 Setting P9 Setting P12 Setting

Isolation DIS DIS DIS

Zone A Page Audio → Monitor Bus EN EN DIS

Monitor Bus → Zone A Page line DIS DIS EN
